Waterlogging & drainage
Excess water displaces air in the root zone
Persistent wet feet can weaken turf and create recurring bare areas.
What to look for
- Standing water or soil that remains saturated.
- Yellowing, thinning or bare areas in low spots.
- Surface algae or moss can accompany persistently damp conditions.
Confirm it before you treat it
Record how long water remains after rainfall and where runoff enters. Check levels, soil layers and irrigation settings. Root disease can occur alongside drainage failure; identify both rather than assume a fungicide solves the site.
What to do next
- Keep traffic and machinery off saturated turf.
- Reduce unnecessary irrigation and investigate drainage or surface-level problems.
- Discuss aeration or drainage work after assessing the soil and a suitable outlet for water.
Conditions matter more than dates.
Poor infiltration, compaction, heavy soil, low spots and excess irrigation can all contribute.
Inspect after sustained rain in any season. Schedule recovery and soil work when conditions and active grass growth permit.
Should I aerate while the lawn is flooded?
Wait for an assessment and suitable soil conditions. Working saturated soil can cause further damage.
